And Lutris is saying that my GPU is “unknown”

In conclusion somehow vulkan isnt working anymore.
Yesterday there was an update for the nvidia drivers which could have broken it but im not sure.
In general yesterday everything went smooth without any errors.
I also checked if some dependencies magically disappeared but I tried reinstalling them but they were all already installed.
If someone has a clue I would be happy to hear them.

I also tried downgrading the latest vulkan packages:
but this also didn’t solve my problem

Seems like you have some defective secondary driver installed. Since you have NV, you probably want to uninstall mesa-vulkan-drivers. Use vkvia to check the installation.
